F. prausnitzii A2-165 also exerted anti-inflammatory effects on both cellular and colitis animal models by blocking NF-KB activation and IL-8 production (Sokol et al. 2009), facilitating the induction of IL-10 in human and murine dendritic cells and modulating T cell responses (Rossi et al. 2016). Here, CXCL8 is linked to colitis.
